The Fourteenth Annual Spring Institute on Noncommutative Geometry and Operator Algebras (NCGOA) took place in Bonn, Germany, during the Hausdorff Trimester Program "Von Neumann Algebras". It was a combination of spring school and international conference. During the school part of the meeting, which coincided with the introductory school of the trimester program, several mini-courses were given by leading experts. The conference consisted of a number of invited research talks.

Sponsors: Funding for the Fourteenth Annual Spring Institute on Noncommutative Geometry and Operator Algebras was provided by the US National Science Foundation through grant DMS-1600819, both the College of Arts & Science and the Department of Mathematics at Vanderbilt University, and the Hausdorff Research Institute for Mathematics. We are grateful for their support.
